AWEA Issues Fourth Quarter 2017 Market Report

LCG, January 31, 2018--The American Wind Energy Association (AWEA) recently released its new U.S. Wind Industry Fourth Quarter 2017 Market Report. AWEA reports new wind turbine installations have added 4,125 MW of electric generating capacity during the fourth quarter, bringing year-to-date installations to a total of 7,017 MW. There is now 89,077 MW of cumulative installed wind capacity in the U.S., with over 54,000 wind turbines operating in 41 states plus Guam and Puerto Rico. In addition to new installed wind capacity, 2,136 MW of partial repowerings were completed during 2017. At this pace, the installed wind capacity may soon exceed the total nameplate capacity of U.S. nuclear generating units, which now total approximately 105,000 MW.

Texas continues to lead the U.S., with a total installed capacity of 22,637 MW. Oklahoma, with 851 MW installed in 2017 and a cumulative total of 7,495 MW, has now surpassed Iowa, with 7,308 MW. California (5,609 MW) and Kansas (5,110 MW) retain fourth and fifth place ranking.

AWEA estimates that the combined wind power capacity under construction (13,332 MW) and in advanced development (15,336 MW) is 28,668 MW. Of this new capacity, 30 percent of all activity is located in the Midwest region, 21 percent is located in the Plains states, followed by 20 percent in the Mountain West states and 20 percent Texas.

Four wind turbine companies dominated the installations. GE Renewable Energy, Nordex USA, Siemens Gamesa Renewable Energy, and Vestas captured a combined 99 percent of the U.S. turbine market for new installations during 2017. Moreover, GE Renewable Energy installed 79 percent of the partially repowered capacity in 2017.
